To all who-m. it may concern Be it known that I. \VrLLLur Knocns, a Unit-oil State rosiding in l lrooldyn, county of King's, n'tntc of New York, have invcn'tcd certain now and. useful lnrjormen'ients in Pro ms, of which the foiloinng a specification.

This invention relates to powcr prcsscs, and more cspccinlly to presses designed for it rims to prondc .nnprovs merits there-in. "lhcprcscntinvention has becn based upon cxpcriencewith presses in which pressures oflEOO tons and over are delivered by the lra cticnl limitations in the sizes s and material are almost rcnched in pressts of the above-mentionedcapacity. The demand is for still larger presses. l urthcrmore, owing, to the enormous strains ('lcvclo-pecl in pro :es of .largc' capacity the amount of. deflection or distortion of the parts owing to the-side thrust transmitted from the crank shaft to the plunger through 'the connecting rod-{when the vcnlnks are off cont-er is so "great as to introduce very serious problems in the designing of such By thc prc'scnt' invention means are pro- Tiileti for ovcrcoming the foregoing objections. r

Embodimcntsof the invention are illusviews; and Fig. 5 shows a transverse section of a. portion of the construction illustrated in Fig. 4..

Referring first to Figs. 1, 2 and 13 ot said chine, B the bed, the reciprocating plungcr. and D a p-l'u,ra-li t. of tic-rods connect 1! the framc bed, and constituting n ignzrto a plurnity of crank shafts nrrzngecl fthc frnmc instead of longi in present constructions.

cranks E. E E, E are rotated from a drive shaft G through a suitable train of, .redncing genrs and pinions g, g, g, 9 9f, {1" and the gears g, g", g", 9 An even number of crank shafts E, E E E is 'prsfcrnbljiprovided, and they are so arranged that the diagonal thrust transmitted to the nlungcr from one crank shaft when off center will be counteracted by that of another. They are, furthermore so arranged that tho total effect of the diagonal thrusts of the crank shafts is to exert a'conipressing stress trans\ 'erscly of tho plunger,. rather than a tcnsionnl stress. As shown inthc drawings, the two shafts .E and .E a-re adapted to rotate both in the same direction and the shafts E and E are adapted to-rotats both in the same. direction and in the opposite direction to the shafts E and E thereby counteracting thc diagonalthrust transmit-ted to the. plungrcr from t e crank shafts E and E whcngoflf ccnten. -The remcshing with the gears g andkgf an'd and g of each pair of crankfshafts. Any number of pairs of crank shafts may beprovided. The connecting rods prelt'cmbly have their ends f fittcdin sockets f in the lower side of the plunger and may no rcpins f. (See Fig. The ends f of the plungcr nrc also preferably providcd with broad side. faces P which closely engage the uide'faccs of the sockets and thorcby serve to counteract any transverse rocking of the plungcr.

The n.css is prcferzibly udiiptcd to have switions added thereto at its ends, when it is desircd to lengthen the press. For this pur. pose the ends of the plungerand bed may be dove-tailed at Lon-:1 have fitted thereto. bed and plunger sections .T andK of another section of pr and the rotation of the crank shafts is, preferably such that the stresses bots-con the sections of the-plunger will compre =ivc rather than tensilc thereby relieving the connection of strain.

In Figs. 1; and 5 of tho drawings is shown COHSITllCtlUIl wherein structural iron or steel is used for the frame, and comprising plurality of longitudinal I-bcams or girders L L nnibd by transverse Webs or plates M :nrecl to the Lbs-rims by bolts and flanges. This construction is of advantage tation of the shafts, as described.- bore is. effected by means of the pinions'g and g v I tained in thc sockets by means of t-ransvcrsc.

' tions and changes may be made therein withtron.

What is claimed is:

1. In a power press for heavy work, the combination of a plun er, and a plurality of out departing from the'spirit of the invencrank-shafts eonnecte to said plunger, and

means for rotating said shafts in opposite directions whereby the diagonal thrust transmitted to the plunger by one crankshaft, whenoll' center, Wlll be counteracted by that of another, eachof said crank shafts being continuously rotatable in one direction.

, 2. In a power press for heavy work, the combination of a plunger, a plurality of crankshafts, connections between said crank-shafts and said plunger, and means for rotatin said shafts in opposite directions where y the diagonal thrust transmitted to the plunger by one crank-shaft, when oil center, will be counteracted by thatof another, each of said crank shafts being continuously rotatable in one direction.

combination of a plunger, a plurality of crank-shafts, crank connections pivotally connected to said plunger upon an axis perpendicularly above that of said crank-shafts, and means for rotating said shafts in opposite directions whereby the diagonal thrust transmitted to the plunger by one crankshaft, when off center, will be counteracted by that of another, each of said crank shafts being contimiously rotatable in one direction.

4. In a power press for heavy work the combination of a plunger, a plurality of crai-ik-shafts connected to said plunger and means for rotating said shaftsin opposite directions in pairs, whereby the diagonal thrust transmitted to the plunger by One. crank-shaft, when off center, will be conntcra'ctcd bythat of another, each of said crank shafts being continuously rotatable in one direction.

- 5. In a power press for heavy work, the combination of a :plungcr, a. plurality of crank-shafts connected to said plunger.

gears on said crank-shafts, and pinions engaging gears on pairs of crank-shafts and rotating said gears on one pair Ill an opposite direction to those in another, whereby the diagonal thrust transmitted to the n a power. press for heavy work,-the

plan or by one crank-shaft, when off center, will be counteracted by another.

(i. In a power press for heavy work, the combination of a plunger and bed madein sections and the sections connected together and a plurality of crank-shafts connected to said plunger, and means for rotating said shafts in opposite directions, whereby the diagonal thrust transmitted to the plunger by one crank-shaft, when ofi' center, will be counteracted by another, each of said crank shafts being contiuiously rotatable in one direction.

7. In a power press for heavy work, the combination of a plunger, and a plurality of crank-shafts connected to said longer, and means fcr rotating said shafts 1n opposite directions, whereby the diagonal thrusttransmitted to the plunger by one crankshaft, when off center, will be counteracted by another, said means comprising ars on said crank-shafts, pinions for driving said gears on said crank-shafts in pairs, worm-gears on sa d pinions, a driveshaft, and worms on aid driv='-shaft adapted to drive said wor i'aie' opposite directions.

8. In a power press for heavy work, the combination of a plunger, and a plurality of crankshaftsconnected to said plunger,

and means for rotating said shafts in opposite directions whereby the diagonal thrust transmitted to the plunger by one crankshaft, when off -.cnter, will be counteracted by that of another and in directions to produce a compressive stress in the plunger between one shaft and anotherr'ot-ating in an opposite direction, each of said crank shafts being continuously rotatable in one direction.

9. In a power prcssfor heavy work, the combination of a plunger, and a pluralgy of crank-Shafts, connecting rods, said r s and plunger having inter-engaging parts adapted to counteract transverse rocking of said plunger, and means for rotating said shafts in opposite directions whereby the diagonal thrust transmitted to the plunger by one crank-shaft, when oil center, will be counteracted by that of another, each of said crank shafts being continuously rotatable in one direction.

10, In a power press for heavy work, the cmnhination of a plunger, and a plurality of crank-shafts connected to said plunger, and means for rotatingsaid shafts in opposite directionswhereby the diagonal thrust transmitted to the plunger by one crankshaft, when olf center, will be counteracted by that of another, each of said crank shafts being continuously rotatable in one direction, all said crank-shafts on one side of the center line of the press rotating in the samedirection.

ll. In a power press for heavy work, the
